1. A system for reducing the risk of loss or theft of a cellular telephone, the system comprising:
- a cellular telephone including;
(a) a cell phone battery, (b) a wireless cell phone transmitter for voice and DTMF communication with distant phones, pagers, and/or computers via a cellular telephone network, (c) a demodulator for demodulating incoming voice signals; and
(d) a security wireless transmitter for sending wireless security signals to a device to be worn or carried by the user, said cell phone battery supplying power to each of said cell phone transmitter, said demodulator, and said security transmitter;
said device to be worn or carried by the user including (i) a battery, (ii) an alarm, (iii) a security controller, and (iv) a first wireless receiver for receiving said wireless security signals sent from said security transmitter of said cellular phone, said battery in said device to be worn or carried by the user supplying power to said security controller, said alarm, and said first receiver;
wherein said security controller in said device to be worn or carried by the user includes means for actuating said alarm in response to one of;
(i) the wireless security signal received by said first receiver from said cell phone being of a strength or amplitude below or equal to a predetermined threshold; and
(ii) no wireless security signal above the predetermined threshold being received by said first receiver from said cell phone for a predetermined period of time, whereby the user is alerted to cell phone misplacement, loss, or theft by actuation of said alarm;
wherein said device to be worn or carried by the user includes a pager for receiving wireless paging message signals from a telephone system indicative of a calling party'"'"'s number, said pager further including (v) a second wireless paging receiver for receiving said paging message signals, said second receiver being powered by said battery in said device and being separate and distinct from said first receiver; and
(vi) a display for displaying data relating to received paging messages, said display also being powered by said battery in said device.

Abstract
A system and method for reducing the risk of cellular phone loss, misplacement, and/or theft, the system including a wireless transmitter in a cell phone for intermittently sending security signals to a device (e.g. pager) to be worn by a user. The device includes an alarm which is actuated when either the strength or amplitude of the security signal(s) falls below a predetermined threshold or when such security signals are not received by the device (e.g. pager) for a predetermined period of time. Accordingly, the user is alerted to potential loss, misplacement, and/or theft of the cell phone.
